SEGA CDX REPAIR HELP!!!! NO POWER

[Crisis_Charlie]

My Sega CDX was acting up and wouldn't read disks I opened it up cleaned the lens and cleaned out the dust inside. I test it out and out to my surprise it starts working fine, relieved and happy I try and put it all back together and somehow unhook a fuse that was connected to the shield inside, now it will not power on at all I have tried everything and can't figure out where that shield was connected to the board and which fuse I could use to replace it. Please help me out here this thing was not cheap.
